The company previously announced to employees internally on July 11 that certain markets, such as China, Denmark, Indonesia, Philippines and South Africa, among others, will cease to have Handy services.

“We recently wrote to notify you that, due to operational changes, Tink Labs will no longer be supplying or servicing Handy smartphone devices in your geography,” read the email sent out to Thailand and Moroccan hotel clients. “We can now confirm that cellular service to these devices will be terminated over the next 6-12 hours.”

Hotels in Hong Kong and Singapore were informed that their contracts with Tink Labs were being reassigned to a separate entity, Blockone Limited, and that in the process of transferring the responsibility, “cellular connectivity will cease being provided over the next 12 hours”.

The new entity, Blockone, will also cease to provide its Handy devices to certain hotels in Hong Kong for free.

In early July, Tink Labs informed employees that operations would cease August 1, according to multiple sources who asked not to be named as the information is private.
